  • Preparation of Papers for AIAA Journals
    Analysis of Satellite Radio Occultation Architecture and its Stakeholders I. Josue Tapia-Tamayo1 and Paul T. Grogan2 Stevens Institute of Technology, Hoboken, NJ 07030, USA Global Navigation Satellite System Radio Occultation (GNSS-RO) is a technique that relies on the change of a signal transmitted from a Global Navigation Satellite System (GNSS) as it passes through the planet’s atmosphere. This technique is not only suitable to study weather forecasting or climate change, but also offers a low-cost application. This report aims to characterize and parametrize the system architecture of commercial companies pursuing the Commercial Weather Data Pilot (CWDP) contract by the National Oceanic and Atmospheric Administration (NOAA). The approach of the paper will start by explaining the Radio Occultation technique and its potential application to Numerical Weather Prediction (NWP). The paper then identifies the main stakeholders of radio occultation and NWP, and their needs. Some key functional requirements are pinpointed, and the challenges that some of these architectures must overcome is discussed. Introduction The increase of severe weather in the last decade has led to the need for improvement of U.S. weather forecasting. Severe weather such as hurricanes and flooding causes great economic damage to cities. According to National Oceanic and Atmospheric Administration (NOAA), the cost of economic damage caused by hurricanes was $161 billion for Katrina in 2005, $71 billion for Sandy in 2012, $125 billion for Harvey in 2017, $90 billion for Maria in 2017, and $50 billion for Irma in 2017. The overall cost of hurricanes in the U.S. reached $515.4 billion in insured property losses from 1986 to 2015.

For more details, see the information below. Photo credit: Image courtesy of ULA. ULA On Feb 22nd, ULA posted the following blog announcement. “At ULA's Vertical Integration Facility (VIF) on Monday, Feb. 15, the Vulcan Centaur program achieved a significant milestone when the Pathfinder Tanking Test (PTT) booster was hoisted into place aboard the Vulcan Launch Platform (VLP). PTT is a flight configuration core stage that will complete validations of the launch site and later be used on a Vulcan Centaur launch into space.” Earlier in the month, a pathfinder first stage that will pave the way for Vulcan Centaur's inaugural launch arrived at Cape Canaveral from ULA's factory in Decatur, Alabama, to begin launch site testing of the next-generation rocket. The Pathfinding Tanking Test (PTT) booster, a flight configuration Vulcan Centaur core fitted with a pair of BE-4 development engines, was produced using the advanced automation and tooling in Decatur that is designed for maximum efficiency and reliability. INMARSAT On Feb 24th, Inmarsat announced the appointment of Rajeev Suri as CEO replacing Rupert Pearce.

  • CWDP) Round 2 Summary
    NOAA/NESDIS Commercial Weather Data Pilot (CWDP) Round 2 Summary June 2020 Commercial Weather Data Pilot: Round 2 Summary June 2020 Background Radio Occultation (RO) is an established method for remote sounding of the atmosphere. The technique uses an instrument in low-Earth orbit to track radio signals from Global Navigation Satellite System (GNSS) transmitters as they rise or set through the atmosphere. The occulting atmosphere refracts or bends the radio signals, and given the precise positions of both satellites, the bending angle can be deduced from the time delay of the signal. Collecting these measurements for a full occultation through the atmosphere provides a vertical profile of bending angles, from which profiles of physical quantities such as temperature, humidity, and ionospheric electron density can be retrieved. These data primarily feed numerical weather prediction (NWP) models that support weather forecasts, and also support space weather applications. Deployable on small satellites, RO instruments complement microwave and infrared sensors, fill in the sparse geographical and temporal coverage of radiosondes, and provide vertical and temporal resolution complementing other satellite observations. Weather centers currently ingest thousands of RO profiles per day from various government satellite systems. Studies indicate that increasing the quantity of RO data, particularly in orbits and times not served by government systems, would further improve forecasts. Ionospheric observations from RO sensors also enhance space weather situational awareness, revealing variations in the ionosphere that impact GNSS performance and radio communications. Beyond these direct benefits, additional sources of RO data could provide risk mitigation for any unexpected reductions in other data streams. NOAA began assessing the potential of commercial sources of RO data in 2008 as part of contracted studies to assess a variety of commercial capabilities.

    2017 Spire Global, Inc. Orbital Debris Assessment Report LEMUR-2 Satellites Phase IC (with Hosted Payloads) and Phase II Revision History Revision Description of Revisions Release Date 1 Initial Release 10/13/2017 An orbital debris risk assessment of LEMUR-2 Phase IC (with hosted payload) and Phase II satellites Section 1: Program Management and Mission Overview Program / Project Jenny Barna Manager Mission The purpose of the LEMUR-2 satellite constellation is to provide high-revisit global maritime and Description aircraft domain monitoring data, weather data, and hosted payload services. This orbital debris risk assessment report (“ODAR”) covers any LEMUR-2 Phase IC satellites with a hosted payload and Phase II satellites proposed to be launched by Spire Global, Inc. (“Spire”). Foreign None Government Involvement Project Milestones LEMUR-2 satellites are usually launched in small deployments depending on available capacity, quality of orbit, service and constellation replenishment needs, and risk profiles of the launch Proposed vehicle and campaign. Launch Date Given the potential long lead time for the instant application and state of the low-Earth orbit Proposed launch market for secondary payloads, Spire is filing this application early and is not capable of Launch Vehicles providing launch parameters for the Phase II satellites at this time. However, it notes that these satellites (similar to the Phase I, IB, and IC satellites) will only deploy at orbital altitudes from 385 Proposed to 650 km and inclinations ranging from equatorial to polar sun-synchronous (98 degrees). Launch Sites This analysis considers the range of representative orbits and includes a debris assessment of the Launch Vehicle worst-case altitude and lifetime in order to provide the most conservative results.
